Studies of τ mesonic decays are presented. A mechanism for axial-vector current at low energies is proposed. The VMD is used to treat the vector current. All the meson vertices of both normal parity and abnormal parity (Wess-Zumino-Witten anomaly) are obtained from an effective chiral theory of mesons. a 1 dominance is found in the decay modes of τ lepton: 3π, f (1285)π. Both the ρ and the a 1 ...

Weak radiative decays of beauty baryons into strange baryons, induced by the elec-troweak penguin, are estimated by using a quark model approach. Relations between formfactors in the semileptonic and in the weak radiative decays are derived within the heavy quark effective theory. The partial decay widths are found to be of the order of 10 −15 MeV for Λ b → Λγ and Ξ b → Ξγ and of the oder of 10...
